# Hyperbolic Dynamics, Fluctuations and Large Deviations

Share this page *Edited by *
*D. Dolgopyat; Y. Pesin; M. Pollicott; L. Stoyanov*

This volume contains the proceedings of the semester-long special
program on Hyperbolic Dynamics, Large Deviations and Fluctuations,
which was held from January–June 2013, at the Centre
Interfacultaire Bernoulli, École Polytechnique
Fédérale de Lausanne, Switzerland.

The broad theme of the program was the long-term behavior of
dynamical systems and their statistical behavior. During the last 50
years, the statistical properties of dynamical systems of many
different types have been the subject of extensive study in
statistical mechanics and thermodynamics, ergodic and probability
theories, and some areas of mathematical physics. The results of this
study have had a profound effect on many different areas in
mathematics, physics, engineering and biology.

The papers in this volume cover topics in large deviations and
thermodynamics formalism and limit theorems for dynamic systems.

The material presented is primarily directed at researchers and
graduate students in the very broad area of dynamical systems and
ergodic theory, but will also be of interest to researchers in related
areas such as statistical physics, spectral theory and some aspects of
number theory and geometry.

#### Readership

Graduate students and research mathematicians interested in dynamical systems, ergodic theory, statistical mechanics, and mathematical physics.
